    115 6c TOP piston cylinder issue

    Thanks for the additional details on what it does. Ive got a lot of work to do, but will do this after i go through the carbs

    115 6c TOP piston cylinder issue

    That is interesting! i never knew what those little hoses were for. I figured it was part of some deep black art I wasn't meant to know. Ive only been using non ethanol gas, so I would imagine that makes the particular effect at least a little less pronounced. I was also thinking you could put...

    115 6c TOP piston cylinder issue

    Good news! sound someone who can do it. I'm assuming he is gonna try for .03 on 3 and 6, but will wait to talk to him when he has block in hand. Will update as i know

    115 6c TOP piston cylinder issue

    Thanks. I’m trying to set up a path to not just fix it(assuming I can get someone to rebore) but also to be aware of possible issues. I bought the motor about 7 years ago, but it did not have a repair history. I am thinking that 1,3, and 6 have been rebored because they are all .015s. I...

    115 6c TOP piston cylinder issue

    Waiting to hear from the machinest. Ive been going through pieces of the engine I have here. The reedvalves facing cylinder 3 were a little out of spec. There were a couple of petals that were probably .009 or .01. Im trying to understand things that could have contributed to losing the...

    115 6c TOP piston cylinder issue

    It seems so. The trick is finding someone who knows how to do it and will take it on. I followed every lead I could find and they were all dead ends. And I live in the seattle/tacoma area, so I thought it would be easier. Waiting to hear if the machinest’s buddy can do it

    115 6c TOP piston cylinder issue

    I got to machine shop and the guy couldn’t bore a blind cylinder. He felt bad(I drove 2 hours to get there) and is gonna reach out to another machine at he thinks can do it. It’s wild that this is so hard to find. Anyway.. Will post when I find anything out

    115 6c TOP piston cylinder issue

    I made a valiant effort to measure the bores but I just don’t have the right equipment. I’m taking it to a shop to measure and recommend a course of action. The only cylinder damage I can see is a small scrape in 6, but I can’t tell what has happened beyond that. I think 1,3, and 6 are all .015...

    115 6c TOP piston cylinder issue

    I think both 3 and 6 are bad. I spent 2 hours calling machine shops today and finally found one that can look at it..

    115 6c TOP piston cylinder issue

    OK. Got crankase out. I'm hopeful. Cylinder 3 actually looks pretty good. Cylinder 6 has about a 1" scratch that barely catches my nail on the right side. I tried to get pictures of the cylinders, but couldn't get the lighting right to capture them. Here are the 2 funky pistons. 3 is totally...

    115 6c TOP piston cylinder issue

    progress. I was getting a little confused, as you were saying i didn't need to pull flywheel, but i could not get a wrench around the end cap screws without pulling it. Got it off, and got crankcase open. I'm gonna do a little reading, clean up the shop, and get organized before i start digging...

    115 6c TOP piston cylinder issue

    Please forgive my ignorance-- This is the first time to split a motor. The top end cap in underneath flywheel(and i assumed stator). I can't get the endcaps off without removing this(at least don't think i cant) My comment about connector rod and caps is concerning being able to reattach...

    115 6c TOP piston cylinder issue

    I was under assumption that flywheel needed to come off to get top endcap off. I can't see a way to get to it with it on. I'm gathering info from reading and watching videos. I know these earlier engines had the rod caps with the nuts below. Would this make attaching pistons to crankshaft...

    115 6c TOP piston cylinder issue

    I was just being cautious with end caps. I have never take them off before. rebuilt carbs, fuel pump, and did a link and sync when I got motor 6 years ago. Up until the end of last year motor has performed admirably. I looked at the tube and it all seems fine. Motor has always had a good...

    115 6c TOP piston cylinder issue

    Hey everyone. Posted an initial query, but now diving in deeper and wanted to post a more comprehensive thread. mid 80's 6c TOP 115. s# 6525632 Started out with 0 compression in cylinder 3. Powerhead off. Goal is to hopefully get engine going, but worst case, to learn a bit about it. I think...
