Hi Guys,

Hope someone can shead some insight into this problem of mine........... i flew my tigershark today which is in the pic below....... its powered by a Leo 46 2 Stroke engine.......... now to the problem....................

1) Not sure about what the best prop size i should be using at the mo i currently have a 11 x 6..............
2) The engine doesnt seem to peak, its a new engine but just doesnt sound like its peaking like my other 2 strokes.
3) With the glow plug off the engine turns fine........ when the glow plug is on a clicking is heard and its VERY stiff not every turn but once every 3 turns say its extremely stiff...... but like i said with the glow plug out it turns without clicking......... i looked at the engine and i can think is the glow plug too long and is hitting the engine when the cylinder reaches the top ?????? is that whats causing the click as it makes it when it hits compression.... but im using a OS 8 Glow plug, soo im not sure if u can buy shorter ones or even if this is the problem...................

Any help or insight into any of these above points will be very helpful........

Cheers guys.......
