jifffy auger problems

[fast40m]

I have had a jiffy model 30 for 5 years. It has been to the shop more than to the lake. I found out today that if I cover most of the holes by the recoil, It runs like it should. Is there a fix for this? Can I tape over the holes without hurting the engine? Has anyone had this type of problem?

Thank You

Well after setting my high and low speed adjustment screws the way the guy told me on the phone, my auger wouldn't even idle. So then I thought maybe he got them backwards. So I turned my low speed 1 turn, and I finally got it to idle. Does anybody know if the high speed is about 1 1/2 turns? I know I won't know til there is a load on, but I would like to be in the ballpark! Also to tweak it to run better, which way do you turn it? Back in? Out? I never did real good in shop class!

Its just one of those things your ear gets tuned to but I'll try and discribe it. Make very small adjustments(1/8th turn).

Your better off running on the rich side. For one it takes more gas to start a cold engine. Leaning the idle mixture down will only make it hard starting.

Turn the idle mixture screw out till the engine idle starts to slow down, note that position then turn the screw in till it starts to run smooth. Now turn the screw out till it the RPMs just start to come down, leave it there for now.

Like I said earlier you need to put a load on the engine to get the high speed mixture correct but for now get it to build RPMs nicely without a load. When you hit the throttle it should wind up right away with no hesitation, no bog and no popping. If it bogs your most likely to rich, if it pops your to lean. If its smoking like crazy with hesitation then eventually builds RPMs its too rich. Turning the mixture screws in(clockwise will lean it and of coarse out(counterclockwise will richen the mixture. I like to come in from a rich mix and hit top RPMs then back it out till it starts to drop.

Now get it on the ice and test drill. All your adjustments will be with the high speed mixture screw. When you get to where it should be you'll have no bog, popping or hesitation. You'll hear the governor kick in as you put more load to the engine almost like its shifting gears.

Remember its better to be rich then lean. The engine will last longer and start better when properly adjusted carb and for heaven sakes, its a 2 stroke so its going to smoke.

Thanks Frank!

I will see what damage I can do tomorrow!

I sure wish that "Big Lake" of yours would freeze over. My friend is in Duluth, and we are itchin' for some looper action. Also, then I only need the spud!

Thanks again!
