Saving Old Seagulls

could be a couple of things but make sure that the choke is working and that it is fully shut when you are starting the engne.

yes... that is the correct prop. there is also a 5-bladed 11" prop that will suit that model. dont know too much about racing myself but i would imagine a smaller and faster prop and gearbox would be more suitable.

yes.....just a matter of being careful with maybe a little oil. you can use a little moderate heat to expand them a bit if you need to. even standing them in boiling water fora few minutes should help.

just make sure when you insert the piston into the cylinder that you have the rings fully compressed and that their ends are pushed against their respective pegs which are located on opposite sides of the piston.a little lubrication wont hurt either.....DONT BREAK THE NEW RINGS!

maybe you have the right tank and the wrong block and/or carby! which model are we talkig about?

i put some kerosene (paraffin) and a couple of cupfuls of perllite(fish tank stones) in a tank and lashed it to the rotisserie of my barbecue and let it run for a full day........clean as!!

well that makes sense......but it now sounds like senor happy seagull has problems other than plugs!

my apologies...i misread the data. it seems the two plugs are identical in all ways! http://www.championsparkplugs.com/resul ... 6&x=51&y=6

they are same thread and heat range but 7/8" reach according to a champion plug site i found

welcome amigo.......the two plugs are identical except that the RD 16 has nearly double the reach of the D 16 which is the correct one! the engine certainly would give you a problem with the longer one! cheers......... and may your gaviota stay alegre!

hugz is probably right there. i was working on the assumption that the exhaust tube would detach itself as soon as there was any separation between block and crankcase after which the block should be able to lift slightly to allow this to occur. have never actually done it this way so if i am wrong ...

you have helped me greatly guys.......many thanks!

ok......thanks for trying john. somebody definitely did make them though because i saw one yesrerday.bloody mystery!

not absolutely necessary but it is only 2 nuts to undo and makes it a bit easier to wriggle the piston into the cylinder

would anyone happen to know which company makes or made these plugs? i cant seem to find one anywhere
