You can either jb weld the barb to plug it or twist it out with pliars and plug the hole with a screw. A regular decomp valve will thread right in to the cylinder.
First off sorry OP, I'm not trying to hijack your thread but does it take a special fitting to plug the decomp? I picked up a 357 last fall but haven't put much time on it, it had been sitting for a while apparently and when I ran it it seemed to warm up and not run properly. I assumed it had crap in the carb, gummed up, maybe bad fuel line and filter. I replaced all that with new air filter and plug but still acted up.
It would bog down when I hit the throttle and wanted to die as well. I took it into a shop to have them check it out and they went through it I got it back and it seemed fine till I ran it hard then started acting up again. I took it back they went through it again, cleaned carb and tried a new plug and I ran it yesterday. Started fine but had the bog for a lil bit when it was cold, once I got it warmed up good it cleared up and ran like as scolded dog!!! Very impressed with this saw!!!
Does that sound like the decomp acting up? I'm not against plugging it if it will save me some headaches down the road.
By the way this saw is very clean and I don't think it has a lot of run time on it.
I'm wondering if it was the decomp from the get go, maybe stuck from sitting?!?
Thanks for the info in your thread, keep it coming.
Easier if you search squish & base gasket delete. But squish is the clearance between the piston and top of cylinder. You want that the be around .020" and that is usually what you get when the gasket is removed. There are a number of sealants to use at the base of the cylinder.
150 psi is no good with a gasket delete? I get around 190 on a 357.I found some Motoseal at one of the local autoparts stores and I got it back together this afternoon. A quick compression check showed 150PSI. Now I need to mod the muffler and I am ready to start.
Then you need to get a new one lol. Id hate for anbad gauge to cause me to break down an engine prematurelyHum.... I can go recheck. Sometimes my compression gauge is off. Its done it before..
That means it's time to re-read.I've read, I'm just over saturated with info. Its time to start cutting...
That means it's time to re-read.
