Starting when warm.

Post by brian.irwin »

Does anybody know why leaders and arrows will start OK when cold and when hot but do not want to start when they are warm? Is this ccommon or am I doing something wrong. Brian.

All motorcycles have difficulties between cold and 10km, it will thell you how worn your carburetor is.

Here a strange advice; make your carburetor oily on the outside, a 2 stroke will run much better specialy in the winter.

Your pilot jet adjustment may be too rich. When cold, it's like youe choke is slightly on. When hot, most engines do not like any choke.

Re Adrie's comment on oily carb. I've never heard this before. Maybe the oil acts as an insulator, and keeps the cold air off the carb, stopping it from chilling the fuel. Would a little wooly jacket look better than an oily carb?

Actually,it stops ice from forming on the carb,it definitely works,my old man used to do it on his old sidevalve White truck,stopped the carb turning into a ball of ice.If youve never seen a ball of ice next to a bright red hot exhaust manifold,youve missed something.Regards John.

The Dutch Van Veen racing team had 5 Kreidler 50cc machines, 4 of them had 20 HP, 1 had only 17 HP, after a month of testing they found that the rider (Jos Schurgers) had polished the carb. and ports to much, after greasing it up it had 20 HP to.

The sidevalve Whites must have had very good metal in the exhaust valves, because they certainly ran hot exhaust manifolds.
Two strokes don't like flooding when hot. Modern petrol doesn't vapourise like the older blends as it is made for fuel injected engines. Some of the constituients have high boiling points so it is quite difficult to get the starting mixture right. Nev
