BITD (back in the day) I recall Don Pin. (sp?) had a simple HT method that he claimed to use: use a clothes iron as a heat source - what setting? put prop on iron covered up with a small tin can & heat up to max setting for a couple hours ? What temp? ( this before heat guns & the invention of...

The K&B needle valves leak air by the black sinch nut thru the threads on the needle- take the nut off & put a small dab of RTV/silicone seal on end on the brass part that the needle screws into....the plan here is to seal up the threaded area of the needle valve & not leak air into the fuel...

Thanks Rod, I'm well enough - As always, my best to you & yours Rod , will keep in touch- Dave

Rod, Dave Richardson here - I don't usually get into discussions here on the web- but- following along this on con rods, I will with info on the rods that I produced over the years- history: first rods I made were for Vico 19, Ops 3.5, KB40(6.5), Ops 65 motors- This was 1968 ?? onwards- rods...

Some info on these Delta hulls- The first delta hull here (I think?) was the Transonic wood kit from Japan- Boater Bruce Kaiser bought three kits / built them & set / held Saw records in three classes with those boats - B, C, X - Good smart boater that worked hard on his boat programs- got...

.00001" clearance?

New Zealand has a great off shore series in this class of boats - many of the boats raced there are owner built & raced & petrol powered : check it out on : NZMPBA Dave Richardson

I think the boat in the opening page of this was owned by Chuffy Cobb- built & ran by Kevin Behan- impressive sweet sounds out of that as twins were not real popular then..... saw it run at a San Diego race one year.....????memory..... had parts in both those motors- geez......digging back...

Reading with interest this discussion, I will add a bit of info/my thinking- I am no expert & make no claims to be: I think I know a bit about con rods both bushed & roller types from my years of making all types of these parts for nitro & petrol motors- Grahame you know my thoughts here from...

I think twins are sorta like some body once said- it's an addiction- THANKFULLY I controlled myself from that- NOTHING like fuel dragsters lighting off- back in day the SHOW was Garlits........Chitown Hustler funny car.....and THE tops: The Surfers.... Mike Sorokin.....the noise that car put...

Terry- Funny how modelers are now getting 'it' about tuning motors using a low speed needle- The biggest reason I stopped offering the RPM carbs was the endless tuning problems that came up with them. The average boater most often failed to (Could?) understand the tuning with both hi & low...

Gray- How/when did you order the kit? I've been trying for a year(approx.) to order one with no response so far..... it looks very well made & should make a nice model- will guess demand will be high for the kit- Thanks- Dave Richardson

Just think - they breed & steepen the down hill slide humanity is on now into deeper mediocrity- Dave

Rod- I couldn't get thru to your email address- Email me @ [email protected] if you like- Thanks- Dave

David- Thanks- I don't have Rod G's email address- can you forward it to me ? I will email him when I can- I Like the photos of the boat & OB motor - that's what I want & am working toward- Luckily I have a friend here that has an early hull & motor of this vintage that I can measure etc etc...
