Any Chinese chainsaw and chinese parts discussion

[David Young]

Does anyone have significant experience with aftermarket 372 cranks. The big end seems to be a common fail point on even oem. Do the Chinese ones stand the test of time?

 

[Terry Syd]

I've never had any problems with my crank and it is running a heavier piston with the big bore kit. I do run 33 to 1 mix which is likely a good idea for the 372 type crankshaft.

Worked up a huztl 372 topend with a double ring piston and aggressive for me porting lol runs great now I'm going to put a single ring piston in the other when i get a chance i will use the mahle cylinder.

I'm ordering two more one for me and after trying the 365 my friend has to have one now lol

What kind of carb does the saw have? If it is a Zama clone, they are easy to mod to pick up some serious torque, especially if you move to the 77cc big bore kit.

Thanks i've got some carbs to mess with i know i have a hd12 walbro but i would buy a zama if it's easier to mod.

I'm very happy with the huztl cylinder but it does need more carb i will look into that terry syd do you have a link.
They guy that cut bases for me went out of business but i will check it it's got decent comp i did use a base gasket because of excessive porting lol but it's been cold starting on the second pull so the carb seems pretty good I'm only on the second tank with the new topend but like i said it's a keeper.

Here's a link to a long thread over on AS. Poleman fronted up and did the first mods over there and came away with a great carb. You can read through the thread (with pictures) and see how it is done and WHY. The carb far surpassed the HD-12 he was going to put on the saw.

Czed, That looks like a Zama clone on the saw. If you pull it off and open up the 'wet side' (where the metering lever is) and take a picture of the jetting, I'll let you know if you got one of the easy carbs to mod.

Thanks i will Tomorrow it's 8 pm here lol
I appreciate it I've always just used what came on the saws but this there is more to be had with these.

Finally got a chance to cut some i put three tank's through it blocking oak and dead ash excellent midrange and topend power the low end is okay but i will look into the carb mods and might bump the timing up a little but as is very happy with it.

 

[Czed]

I bought two more this morning lol one for me I've got plenty of 372 topends and one for a friend he tried mine and had to have one
Todd said it would last five minutes but I'm up to about three hours on this one we will see if he is right

 

[Terry Syd]

the low end is okay but i will look into the carb mods

If you get around to taking a picture of the carb jetting, we can take a look at it. Hopefully, the saws will be running the Zama twin jet - easy to mod, and the mods will make a difference in the low end torque.
