After close examination of the molded plastic intake, I found many abrupt ridges to smooth out and radii to blend to more gradual transitions within the port. Maybe I’ll shave 1/100 of a second off my cut times now?
That might actually make more sense since the top cover for this saw is cracked anyway. Open that sucker right up and let it breathe
The 400 I have is unmolested besides the muffler mod and it'll stay that way until I sell it. This 370 though has been with me since day one and I wouldn't mind tinkering with it a little at a time. I do like your air filter idea and that's an easy mod. Eventually I'll put a top end in it, port it, and mod the muffler for giggles. I don't mind the idea of having a cheap Home Depot sleeper saw
I found a bunch of oem parts in my shop after working on saws for 40 year's but not enough to build entire saws Topends,carbs,mufflers,ignitions etc. So ordered a couple of holzforma 288s a 372xp a 372xt and a 395 I'm building a couple of the best versions of the 288 The 288 lite lowtop with no longbar spring mount They are not needed on a 24" bar Got a nice am top cover from traverse creek
I broke one of the clutch slide out weights on my 357XP trying to replace the springs so I can idle it up just a tad... My clutch removal tool doesn't fit quite right and I think that my have been what did it. I've had the clutch off several times since I've had it and always used this tool. The break looks like it had been cracked most of the way through before today... I ordered a new (correct) tool and a cheapo AM clutch till I can find someone who has a broken clutch for one of these that they will part with. Just one of the three weight pieces is broken and I'm finding it hard to pay $100 for oem right now. I may weigh the AM weights vs. the two good ones and use one of those if they match or maybe use the slide weights from the AM clutch if they fit the OEM center. Just kind of bummed that I can be my own worst enemy at times. I used to laugh with one of my old buddies that had a cycle shop about how some people just shouldn't own tools... LOL Sometimes I think he was secretly talking about me... LOL
It's a fire and forget type deal i ordered mine on the nov 24 no tracking info for a couple weeks then it popped up On ups tracking they'll be here this week i just checked the tracking The boat landed in California. PayPal will refund if anything happens which I've never had trouble in 30+ purchases I've been running the clone 372s for about 7 year's no problem for me just small parts fuel lines and a couple coils failed and a couple kill switches went bad. Really have been durable saws they've paid for themselves many times over on jobs I gave most of them out to family members to run too many saws laying around here instead of their crap poulans or stihls They really like them. I'm curious about the 395 it was 276.00 shipped And the 288s were only 176.00 each shipped i have a mike lee ported 288 cylinder for one of them and oem cylinders for the other's if needed At all They have good reviews. The 372xp and xt were only 153.00 each shipped.
I’m finally getting into this saw this week. Since the choke is integrated into the air filter, I bought one and a new fuel line and filter, since they were pretty collapsed. Cleaned out the carburetor which was gunked up inside. I got it to fire up briefly on a small squirt of starting fluid. Decided to pull the muffler and So a piston and ring is needed. I figured as much from the start anyway.
Finished cleaning on a Phusqvarna pro 260. It's getting a new ring, bearings / seals, lines and carb kit. Plus ported. Why? Because I can. Lol
The cylinder has a few scores, and definitely some aluminum from the piston transferred onto the walls. There’s plenty of the original cross hatch inside. I’ve got the cylinder soaking in super clean now. I’ll see if I can clean the aluminum off the bore afterwards then give it a light honing. With any luck I’ll be able to reuse it. It appears to be the original cylinder and factory piston. Maybe the last owner ran it too lean on the fuel? Hard to say.
