I was starting to experience the same thing. Matter-o-fact my pressure washer and my lawn mower were all acting the same. Turns out it was crappy gas. TC,... make sure the vent on your gas cap is clear. That will cause the symptoms your experiencing.
Zoood,
All the fuel system has been replaced or checked out ok......new fuel, fuel line. pump electric fuel pump and I went thru the carb......I am going to rebuild the carb as soon as the kit gets here. I don,t think the carb is my problem because it runs great till it gets hot....I am leaning towards replacing the coil....I have read and heard that when the coils are weak ..HEAT makes them act up.....I am also going to heat wrap all of the exhaust and attach an air duct to the exhaust to help more the heat out the back of the rig when moving.....Let me know if you think I am on the right track......Thanks
I forgot about the characteristics of a coil thats heading south. That would do what your saying is happening.

The baffel is coved with SS steel wool and welded inside the 2.5in outer tube. It has little to none backpressure so it should not effect the performance I hope...He are some pics ( paint is still drying) and I will let you all know how its works when I get the rig running next week..

Good idea. That ought to keep the noise down, plus it looks killer! I may have to make something similar for my Hustler...

1982 GMC K-10 Sierra Classic Suburban 6.2 Diesel
2010 Chevy Silverado 1500
1974 Honda ATC 70
1986 Honda ATC 250ES Big Red
There is no Z in Diesel!!
Thanks Stonewall,
The rig is now up and running..rebuilt carb and final tuning complete...Taking it out this weekend for some testing before hunting season...
That looks great,I like the rear winch mount and exhaust and all the other mods you have done.I know you are ready to test it out.
Well the trip up the mountain had its ups and downs. No major problems just working out the rest of the bugs before hunting season. I was up there with two friends on quads and had no problems going where they want to go and then some. I did have some carb issues...the air/fuel screw had a bad leak around it so I could not get the hustler to open up (rpm's) when it was in gear. I was able to fix the problem once I got it home. Did a couple more adjustments to different things and hope to take it back out this weekend.
I have a couple of questions....
1. what is the best way to tune the briggs 18hp for higher elevations ( 9,000-10,500 ft) I live at 5500 ft and it runs great at home..
2.what are the highest rpm's can this briggs take...I adjusted the govenor so I could get the (Oh crap power if needed) not that I plan the rev it most of the time . I do have a tach on it and plan to keep it under 4,000 rpms.

be very careful with the stee wool exhaust. I can get REALLY hot and fall out and start a fire if conditons are right. Easy fix by getting the exhaust off of a dirt bike and using a few spark arrester peices from thatWAY COOL DUDE!
Looks good! Sounds like a pretty successful outing......as with any build there will always be some minor bugs to work out, but it sounds like it shouldn't be too difficult. Again, nice work on the build!
