Evening.
Got a bit bored recently so last Friday I ordered a huztl 372 'spare parts kit' with a 52mm big bore kit. Today it arrived so I've been digging through the box and investigating the contents.
I've been doing a lot of reading on here and a few other sites and watching videos on YouTube to get a bit of an idea of what I should do with it all. I've done a lot of work on cars and tractors in the past, but never bothered with anything 2 stroke, so this will be a bit of an adventure.
After doing a bit of research, I'm going to try to use as much of the parts in the kit as possible to see what happens and carry out a few modifications as I go. I've downloaded the workshop manual and have a 371 to check parts and construction against.
Things I need to do are;
Fiddle with the carb, as the choke butterfly seems sticky and the spring won't close it.
Clean up the cylinder - there's a fair few poor bits of casting and I understand that the ports are fairly restrictive compared to oem. I've bought a flexi extension and some tungsten carbide bits for the dremel to do this.
Clean and oil the crank and big end bearings well, there's a bit of swarf knocking around the bearings and I would like to see them run freely and clean.
I expect I'll have a load of questions which I would be grateful for any advice on. Hopefully I'll get a good selection of pictures during the build which might help others doing this or undertaking maintenance on their own saws.
Here is a picture of the lovely box full of stuff...
Also, a picture of my first question... the seal on the pto/clutch side appears to be larger than the inside of the bearing, and the crank, and I don't expect it is going to actually seal against the crank. I understand that you need an o ring on this side to make it seal, but the gap feels a bit too big really. Is this normal, or have I got a crappy seal?
