Is it OHV? Adjust the valves?

I am impressed how politely answered this question was. It is very very impractical if not totally impossible to convert economically from gasoline to diesel fuel. Like someone said if you have an unlimited budget…have at it

One more thing…sometimes the carb gets so cruddy at the inlet that the float needle sticks and gas cannot enter the bowl. If you remove the drain bolt with the gas shut off open the gas should continue to run through. If only a small quantity of old crappy gas comes out and it stops, your...

I just looked at an IPL for a version of your snowblower. Keeping in mind that the PR241 model is like saying it’s a Ford Mustang when what is needs is a VIN number to get exact parts. There is a much longer number that begins with a 9 that is needed for exact parts matchup. All that said it...

Is this a Honda style carb with two bolts on the bottom of a metal bowl.? If so there is a brass orifice in the center of the carb. It will require a very fine stiff wire, insert the wire up through the orifice and make sure it is open. The wire should be able to insert a full inch to inch...

If there are 2 bolts on the carb bowl. The one at a 45 degree angle is a drain. If there is, remove that bolt and drain some gas out. Catch the gas in a clear container ( old jar?) See what that it looks and smells like. It should be clear and should smell like gasoline not like varnish or...

Have you removed the spark plug and replaced it with a new one or a known good plug? Also try adding some gas through the spark plug hole… replace the plug and attempt to start it. If it pops and runs even for a few seconds you know it’s a fuel delivery problem. I should have asked if the...

So I am not going to get a chance to try to fix this.. my friend called me and said the dealer had called him back and said that when they were looking at his records, they looked at the wrong blower and this blower was in fact under warranty. So he picked it up and is returning it to tge...

I hit the wrong button and sent the above before it finished…. So to get back too it I had the muffler off and cleaned the spark arrester screen and there is nothing wrong with it. I attempted to look at the piston through the exhaust port but it seems that this engine is the Stihl 4 cycle that...

I am attempting to repair a BR700 backpack blower for a friend. My friend brought it to me saying he had it looked at by a local Stihl dealer..who told him it was tied up and needing major engine repair. I removed the spark plug and put an oz. of ATF and a little gas in the spark plug...

Hello I am working on a BR700 backpack blower. A friend brought it to and it was tied up. Rope would not pull. Took the starter off and removed the spark plug and added an ounce or so of ATF-4 and some gas. Worked the crank back and forth a few degrees at a time and it began to move freely...

Yes I misspoke it is acetate. Thanks

Not to answer my own questions. But I just watched a YouTube video on the subject of pump diaphragm materials. I found it searching in my YouTube app ‘Walbro Carburetor Diaphragms’. The guy who did the video identified 3 types. Rubberized which are black and rubbery, Acetone which are the...

I did think it was odd that the lever and spring were not included. I reused the old ones… not ideal. I was thinking that I had read somewhere that the synthetic pump diaphragms, like the electric blue colored one were an upgraded version and replaced earlier styles if they match are the...
