Can someone please tell me the answers to the following.
1.   I have read that an 061 is a bored out 049 and that the crank cases are the same. However I have seen on one web site that the two crankcases have different part numbers.
2.   The serial number on my engine is 8011543. I think that the 80 possibly indicates it is an 049. Can someone tell me the significance of the 11543, possibly the year and Huh
3.   Would anyone have a copy of the original instructions which came with these engines.
4.   I would be grateful of any other data which would be useful.

Hello lesquilant.

Norvel engine is a Russian design but the production license currently has a Chinese company called AP (ASP).

I have one of each, a Norvel Big Mig and an AP Wasp but both are 0.61 cu. in.

Personally I think they are very simple engines and require no more than 20% nitro. Although it is necessary to change the needle valve if you use bladder sistems for the tank. Here in South America experts recommend to add 70 cc. of castor oil per liter of commercial fuel to prevent premature wear.

Maybe help you look at these links.

You got it wrong - 049 and 061 crankcases are different. I know that for a fact - I am a factory rep. So if you need Norvel parts or engines, please contact me directly at [email protected]

The o.d. of the 049 liner is 12.0mm and the 061 is 12.80mm.You can bore the 049 out to fit the 061 liner-I did mine with a rotary burr mounted in the drillpress but a mill will do a nicer job.For spares in Australia contact Scott at Ace Hobbies Midland WA he has a stack of original 061 and 049 Norvel spares but they are all Big Migs not the high performance AME.

Hello lesquilant.

Do not spread the false information - ASP never had a production license - they just stole the design. Norvel is produced in Russia under a new brand NV.

Ok, seems I'll have to reply to a comment from a year ago.
My comment was referring to information that an importer of these engines gave me several years ago. I understand the reason for his comment, but I hope not misunderstand me, not trying to spread anything on that matter that you call stealing anyone had said anything until now.
