Well I checked the boots didn't pull the carb off the boots are pliable and dont appear to be cracked. There is some residue on the carburetor and boots. I read somewhere about people using carb cleaner to diagnose air leaks similar to the way you find vacuum leaks on a automotive engine. Is...

Okay I'll check there. In your humble opinion does it sound like an air leak?

Hey guys hoping to gain some knowledge without having a possible expensive mistake. Some of you may know that I recently lost the top end in my 55 rancher so when I narrowed my dad's 455 and it was acting a little funny I took notice. Maybe I'm a little gun shy but I'm trying to be proactive. So...

Yep the pin that orients the piston ring faces the intake port.

Okay gotcha that's basically what I was thinking. I'm not sure what's up with the hi speed needle on the carburetor something seems funky but maybe it's just a different design. Low needle turned out 1.5 turns hi needle bottomed out. On my other carburetor both needles at 1.5ish give or take are...

Okay tested the new carburetor it will not hold any pressure at all. The old carburetor holds pressure with no issues. So that being the case what should I look for in the new carburetor that would cause it not to hold pressure?

I didn't mention the cleaning of the carb because I had bought a new replacement carburetor for it. However the new carburetor which is a walbro has an issue with it in the metering circuit I think that was causing the saw to pull in so much fuel it was pouring out the exhaust. Upon inspection...

Okay yeah I rubbed the bore down with 2 stroke oil and soaked the piston before reassembly. I think you guys might be right on the missing plating I'm not used to cylinders with only a thin hard plating. I guess I'm going to have to try and source a cylinder that's in better shape and just...

Sorry guys somehow I posted the pictures twice. I learned it is hard to get good pictures of the cylinder bore. One other thing I forgot to mention is about the prep on the cylinder for clean up. I used muriatic acid and 800 grit sandpaper to get the heavy galling off the cylinder walls. After...

Thanks for all the replies guys I thought I was had it clean but I might have dropped the ball in that department. I hot tanked the cylinder and then sprayed it down with brake clean. The crankcase cleanliness could be suspect there was a little grime in there I sprayed brake clean in there and...

Hello folks of aboristsite long time prowler first time poster. Anyways down to the problem I'm facing. So a while back I was given a 1996 husqvarna 55 by my dad. He didn't use it much and always took meticulous care of the saw so it was a total surprise to us when a visit to the saw doc...
